change temperature in one single transient simulation

Hi 

I know we can change temperature in one single transient simulation by using the Dynamic Parameter and put "Parameter Name" as temp.

There are two options there: One for Parameter Vector (that we can input the time step and temperature) and I am fine with option.

Another option is to include a parameter file. But I don't know the format for the parameter file. Could anyone show me some examples for this? If you could show me two examples: one for temperature and one for a general parameter (say for voltage levels for a DC source, etc), that would be great. 

Thank you very much.
